<Callout type="IMPORTANT" title="IMPORTANT">
Information valid only for *Sensedia API Management v5* customers.
If you are a customer of earlier platform versions, see how to [obtain the authorization URL using the Sensedia API Platform](/docs/events-hub/authorizations#obtaining-the-authorization-URL-using-the-Sensedia-API-Platform).
</Callout>

To ensure security in the receipt and distribution of events, only authorized publishers can send events to the Events Hub.

To authorize publishers, you must add security interceptors to the [policies](/docs/events-hub/policies) and configure the authorization URLs on the [Authorizations](/docs/events-hub/authorizations) screen.
When an interceptor is used, the Events Hub sends requests to the registered authorization URLs to validate publishers and accept their requests.

If you are a **Sensedia API Management v5** customer, you must import the Events Hub authorization API to obtain the authorization URL.
